Merge tag 'kvmarm-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm updates for 5.4 - New ITS translation cache - Allow up to 512 CPUs to be supported with GICv3 (for real this time) - Now call kvm_arch_vcpu_blocking early in the blocking sequence - Tidy-up device mappings in S2 when DIC is available - Clean icache invalidation on VMID rollover - General cleanup
